TREE LIFTER Filed Oct. 20, 1927 fltmrmy V Patented June 3, 1930] FRED BUEHLER, OF LINCOLN, NEBRASKA TREE LIFTER Application filed October 20, 1227. Serial No. 227,536.

The present invention relates to a tree lifter for lifting and transferring trees from place to place.

An important object of the invention resides in the provision of a mechanism of thisv nature which is comparatively simple in its construction, strong and durable, thoroughly efficient and reliable in its operation, easy to manipulate, and otherwise well adapted to lo the purpose for which it is designed.

' With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as Will be hereinafter more fully described and claimed.

In the drawing Figure 1 is a side elevation of the mechanism embodying the features of my invention, Figure 2 is a front elevation thereof,

Figure 3 is a perspective view of a lock hook used in connection with the mechanism. Referring to the drawing in detail it will be seen that the numerals 5, 5 denote the front upright supports to the upper ends of which is secured an overhead support 6 with braces 7 connected to intermediate portions thereof and to intermediate portions of the support The numerals 8, 8 denote the rear supports which riseupwardly and converge upwardly toward each other and aresecured together in any preferred" manner. The upright supports 5, 5 and 8, 8 are connected to- 5:5 gether on each side with angle braces 9 and an I beam 10 is supported by the upper ends of the supports 8 and the intermediate portion of the overhead supportfi and has a series of openings 11 in thelower portion of its 3.5 web for the reception of a bolt or "pin 12 to.

function as a block for trolley wheels 13 one on each side of theweb and movable on the lower flange of the beam 10.. These trolley wheels are journaled on the extremities of a Li; U-frame 14 which straddles the lower portion of the I-beam 10. The wheels 13 are beveled to fit the flange of the I-beam. The link 15 is engaged with hanger frame 14 and .supv ports a clevis 16 inwhich is journaled a pulley 17. The numeral 18 denote another pulhay in a clevis 19 supporting a hook 20 with which are engageable loops 21 on the ends of a strap 22. Shafts 23 and 2a are journaled in suitable bearings on the lower portionsfof the supports 8 the former above the latter in spaced parallelism. A winch 25 isfixed to the shaft 23. A gear 26 is fixed to the shaft 23 and meshes with the pinion 27 on the shaft 24:. Theends of the shafts 23 and 2e are squared so that an ordinary crank may be en gaged therewith for winding and unwinding a cable 28 from the winch 25. This cable 28 is trained over a pulley 29'between the upper portions of the supportsS and thenover the pulley 17, and under the pulley l8 and then fixed to the frame hanger 14. "When a tree has been hoisted a lock hook 30 comprising'an elongated shank with hooked ends may be engaged with the hanger frame 1-4 and with the hook 20 so as to relieve strain from the cable 28. i

It is thought that the construction, op'eration, and advantages of this invention will now be quite apparent to those skilled in this art withouta more detailed description thereof; The presentembodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is :r

1. A mechanism of the class described com prising a pair of front uprights, an overhead support on the uprights, a second pair of rear uprights converging upwardly toward each other, an I-beam supported by the mid portion of the overhead support and the upper J ends of the rear uprights, said beam having a plurality of open1ngs, a bolt insertable in said openings, rollers one to each side of the web of the beam on the lower flange thereof, and a hanger frame in which the rollers are web of the beam on and a hanger frame in which the rollers are journaled, said bolt bein adapted to hold the rollers stopped at dierent positions.

2. A mechanism of the class described comprising a pair of front uprights, an overhead support on the uprights, a second pair of rear uprights converging upwardly toward each other, an I-beam supported by the mid portion of the overhead support and the upper ends of the rear uprights, said beam having a plurality of openings, a bolt insertabl'e in said openings, rollers one to each side of the the lower flange thereof,

journaled, said bolt being adapted to hold the rollers stopped at diflerent positions, and said beam being inclined downwardly and rearwardly.

3. A mechanism of the class described com prising a pair of front uprights, an overhead support on the uprights, a second pair of rear uprights converging upwardly toward each other, an I-beam supported by the midportion of the overhead support and the upper ends of the rear uprights, said beam having a plurality of openings, a bolt insertable in said openings, rollers one to each side of the web of the beam on the lower flange thereof, a hanger frame in which the rollers are j ournaled, said bolt being adapted to hold the rollers stopped at different positions, a winch, means for mounting the winch between the rear uprights, a clevis, means for suspending the clevis from the hanger frame, a pulley in said clevis, a second clevis, a pulley in the second clevis, a hook on the second clevis, and a cable windable on the winch and trained over the first pulley and under the second pulley and attached to the hanger frame.

In testimony whereof I aflix my signature.

FRED BUEHLER.
